COLLAR BUTTON.

Application filed June 30, 1926.

My invention relates to a. new and inr proved form of collar button.

One of the objects of my invention is to devise a new and improved form of collar button in which a revolublc member is provided which can be held in the locking position and in the unlocking position so as to positively hold together the two tabs of a collar or to permit their r ady separation.

Another object of my invention is to provide a simple and compact device which shall be cheap to manntactm'e and which will be reliable and etiicient in operat on. Other objects of this invention will be set forth in the following description and drawing which illustrate. a. preferred embodiment of my invention, it being understood that the above general statement of the objects of my invention is intended merely to generally explain the same and not to limit it in any manner.

Fig. 1 is a central sectional view.

Fig. 2 is a top view.

Fig. 3 is an end view.

Fig. 4 is a tront elevation.

Fig. 5 is a section on the line Ii Fig. 1.

Fig. 6 is a view similar to Fig. l but showing the head ot the collar button in the locking position.

The collar button comprises a body member 10 having a curved rear portion adapted to fit the contour of the neck. The body portion 10 has a recess if) in which the shank 12 of the head 11 is mounted.

The shank 12 is pr teral'ily externally threaded and the wall of the recess 1?) can also be internally threaded so as to cooperate with the external threading ol' the shank 12.

The underside of the head 11 provided with tour recesses 17 and these are adapted to be engaged by the detent 15 which is slidably mounted in the recess 14 ot the body 10. A compression spring 18 actuates the detent 15 outwardly. Suitable stops of any well known kind may be employed for preventing the separation ot the members 15 and 11 from the body 10.

lVhen the device is to be inserted through the holes in the tabs of a collar. the head 11 is in the position shown in Fig. 2. After :i (it Serial No. 119,580.

the head 11 has been forced through the hole in the outer tab of the collar, it can be turned ninety degrees, as shown in Fig. ti. in this position it positively prevents separation of the tabs of the collar. Likewise. the detent 15 engages one of the four locking recesses 17 and prevents the turning ot the head 11 to the position shown in Fig. unless the head it is positively actuated by the user,

The recesses 17 are cup-shaped and the top ol' the detent 15 is corrcspondingly rounded so that the detent 1.3 can be forced inwardly when the head 11 is turned. This auses the detent 15 to automatically release and engage the respective recesses 17 when the head 11 is turned.

1 have shown a ')reterred embodiment of my invention. but it is clear that numerous changes and omissions could be made without departing from its spirit.

Since the head 11 can be moved longitudinally with respect to the body 10 by merely turning the said head 11. the device is adjustable tor varying thicknesses ot coltar tabs. The tree outward movement of the detent 15 is sufficient to cause it to cooperate with the recesses 17. when the head '11 is moved inwardly or outwardly with re spect to the body 10.

I claim l. A eollar button comprising a body portion. a head revolubly connected to the body portion. and a detent adapted to releasably engage the head. to cont ol the turning movement of said head.

2. A collar button comprising a body portion. a head having a shank revolubly connected thereto and a detent slidably mounted in the sa d head and associated with a. compi'cssiol'i spring. the said detent being adapted to releasably engage the inner face of the said head. said detent being laterally spaced from said shank.

3. collar button eonnin'ising a body portion having a first recess provided with a th eaded wall. a head having an externally threaded shank which is adapted to fit in the said tirst recess. the said head having a locking depression on the inner face thereof. and a detent slidablv mounted in a second re cess of the said body which is laterally spaced from said first recess. a compression spring located in the said recess and adapted to force the said dctent outwardly. the outer end of the said detent being adapted to re- 5 leasabiy engage the said depression.

4. A. collar button comprising a body portion, a non :ircuiar head having a shank which is revolubly connected to the body portion and a detent connected to the said body portion and adapted to relezisably ene the head. to control the turning moveit of said head.

In testimony whereof I afiix my signature.
